X-energy raises $700M in latest funding round
Advanced reactor developer X-energy has announced that it has closed an oversubscribed Series D financing round of approximately $700 million. The funding proceeds are expected to be used to help continue the expansion of its supply chain and the commercial pipeline for its Xe-100 advanced small modular reactor and TRISO-X fuel, according the company.

Radioactive effluents and concentrations expected from the Clinch River Breeder Reactor (CRBR) during normal operation have been assessed. Developed were the individual off-site dose values as well as population doses within an 80-km (50-mile) radius of the proposed facility. Comparison has been with the as low as reasonably achievable (ALARA) exposure objective as in 10CFR50, Appendix I, of the Code of Federal Regulations. All estimated releases are well within the concentration limits found in 10CFR20. The calculated doses to individuals are consistently lower than values of 10CFR50, Appendix I. Population exposures are a very small fraction of that due to background radiation. Exposures due to CRBR effluents are also in conformity with cost-benefit arguments of the ALARA objective. Measures are in place to follow the design progression and operation of the facility to retain the ALARA aspect of the doses associated with the effluent releases.
